Description

Martin Authentic Acoustic Strings provide unrivaled quality, craftsmanship, and tone for your acoustic guitar. Designed to produce a true, consistent tone, these bluegrass-gauge strings provide excellent tuning stability and playability so your guitar can thrive during your rigorous practice and performance schedule. Made from 80/20 bronze, these strings feature Martin's highest-quality wrap wire for enhanced longevity and durability. They are naturally corrosion resistant, so they will hold up after hours and hours of playing. This total pack of professional-grade guitar strings will last through long jam sessions, late-night campfire songs, and plenty of picking. To make these strings extra-durable and stable, we start with our highest- tensile-strength core wire and then tin-plate it on all 6 strings for added corrosion resistance. When the core is coupled with our highest-quality wrap wire, you get a consistent tone that you can count on song after song. Designed to bring out your guitar's true tone, these bronze guitar strings can be used for finger-style blues, rock, Americana, country, bluegrass, ragtime, and many more styles. With this pack, you'll receive 6 bluegrass-gauge guitar strings. The low E string measures 0.056", the A string measures 0.045", the D string measures 0.035", the G string measures 0.025", the B string measures 0.016", and the high E string measures 0.012".

    • spent a lot of time fretting about this review...
Style: Single Size: Bluegrass, 12-56
I have used Martin Bluegrass strings for many years. They have nice brightness in the trebles, and warm bass notes. They last about like most strings. Solid quality strings from a company well known for their products. I will probably continue to use them. After playing guitar for years, I thought it would be easy to learn the piano. But it's not an easy instrument to pick up... ... show more

    • Strings perform well and last a long time!

These worked exactly as expected. The strings sound and feel exactly like the Martin bluegrass strings that cost much more from other retailers with the American flag on the cover.

I always have been a Martin Bluegrass strings guy. I hate they changed the gauge slightly on one string, but it’s still the best out there even at the nearly perfect gauge strings. Still a 5 star!

    • Very balanced, mellow strings, but not too dull.
Style: Single Size: Bluegrass, 12-56
I bought the 12's, bluegrass series, looking for a set of strings to serve as bluegrass strings. As far as what Martin claims, I think they're an honest pack of strings. One claim of theirs is staying in tune. Here I think they are superb. The strings seem to have an amazing relation to one another and they not only stay in tune, but they tune up very nicely. The octaves sound good together. Initially, I thought they seemed dull compared to other strings, but then I kind of preferred that they werent too loud or piercing. Other strings sound too bright at first sometimes, such that you want to break them in or get them dirty, even. These actually sound very balanced out of the pack. One might wish for a tad bit more oomph to them, but at least it is not overdone. They ebb on the smooth side, which sounds good. I think they would be very good as bluegrass rhythm strings, or even for the general strummer and songwriter. Their mellow, even tone gives a sort of natural compression to the strings which makes each string very smooth when formed into a chord. Everything sounds very coherent and together. The high strings aren't too snappy or loud and this makes for very nice chord tone. Since guitar is very much so a rhythm instrument in bluegrass, this would make them very appropriate strings for the style they claim to cater to. I also think, as Martin claims on the pack, that the playability of the strings is great. They're very easy to depress on the fret. They feel nice. No weird coating or nothing. The only negative I would give them is an unfair one, since these are intended as bluegrass strings: I dont think they're the best for single-note, blues style guitar. Here, the strings sound a little weak, and D'Addarios would probably serve the acoustic blues player better. They dont really have enough focus and volume as single strings and make them come up a little short if one will be playing single note styles outside of bluegrass flatpicking. However, they do bend quite good. I just think the tone is a tad weak for single note blues. Again, they really shine when playing chords. But not all is lost on single note stuff. Bluegrass guitar after all has incorporated lead breaks for over a half a century now, and the strings are well suited for flatpicking and bouncing around the fret board. They have a nice flexibility that allows them to be fretted quite easily. For the bluegrass style, the strings sound fine as single notes. The tone for fingerstyle grew on me. At first I thought it seemed weak. I usually like a lot of bright volume for my finger picking chords. These were at least different in that regard. But then it seemed quite even once again. No higher strings popped too loud and the lows weren't out of place or separate from the rest of the strings. We'll see how long they last. These are first impressions. ... show more
